Night Stalker

"You had better take advantage of the daylight while you can, since come nightfall you will be up against a powerful and adept hunter. Night Stalker's passive Hunter in the Night increases his movement and attack speed at night, making him a feared ganker and chaser whenever the sun is down. His Void spell damages a target and slows them to a crawl, allowing Night Stalker and his allies to deal great amounts of damage. Crippling Fear is a powerful weapon against spellcasters and fighters alike, as it both silences enemies and increases the chance that their physical attacks will miss the target. It is said that you have little to fear from Night Stalker when the sun is high--however, his ultimate ability, Darkness, allows him to instantly turn day into night (or prolong the night that has already fallen), giving his other spells their fullest effect."[1]

The video above walks you through the early stages of the game with Night Stalker. He can do very well mid lane. Getting an early bottle and ganking during the first night is very helpful for your team.

Of the Night Stalker, there is no history—only stories. There are ancient tales woven into the lore of every race and every culture, of an impossible time before sunlight and daytime, when night reigned alone and the world was covered with the creatures of darkness—creatures like Balanar the Night Stalker.

It is said that on the dawn of the First Day, all the night creatures perished. All, that is, save one. Evil's embodiment, Night Stalker delights in his malevolence. He created the primal role of the Night Terror, the Boogeyman, and as long as there have been younglings, his is the specter summoned to terrify them. This is a role he relishes—nor are these empty theatrics. He does indeed stalk the unwary, the defenseless, those who have strayed beyond the lighted paths or denied the warnings of their communities. Night Stalker serves as living proof that every child's worst nightmare... is true.

Night Stalker smothers the sun and summons instant darkness, so that he might use his powers at their fullest. When used at night, it extends night time by Darkness' duration. Upgradable by Aghanim's Scepter.

It is a humbling sight to see when the mightiest of warriors become afraid of the dark.
